    Timing of labs based on different TRT protocols

    From my reading here it sounds on most protocols you draw labs right before your next shot, to get your lowest reading. In my case I inject daily (have low SHBG) with Test C in the morning around 7am. If I usually get labs done around 9-10am in the morning will it show elevated levels if I took...

    OTC Pregnenolone or Pregnenolone through Defy?

    I've been using Douglas Laboratories brand Preg with great results for months now. 25mg in the morning and 25mg again in the late afternoon.

    My bad experience on Cialis (Tadalafil)

    So I decided to try Tadalafil troches 25mg (Cialis) on my last order. Didn't have ED problems, I noticed reading here a few guys use a small amount to get a good pump in the gym. I figured a bigger pump sounds nice and was curious if it could make my hard on's even harder lol. Started at a 1/4...

    Sleep apnea and RBC, Hemoglobin and Hematocrit numbers

    I've asked this question in my intro thread but never got it answered probably because I ask a lot of questions so some go missing. I've noticed my numbers before starting TRT and since being on it have stayed about the same. Am I right to say they are on the high side of ok? Or are they...

    Conversion info for going from 3ml to 1ml syrings

    I started with 3ml syringes. My RX script was for taking 1ml (200mg TestC) once a week. I started with spacing that does out in half. So I used to bring it out to the 1/2ml mark for 100mg of TestC. Later I brought my does down to 80 so I would go to the mark before 1/2ml. Now that I'm looking...

    Hello everyone, To start I just turned 37 years old. I'm 6'3" and 215 pounds with id say around 15-20% body fat. I've taken Zoloft a SSRI since I was a teenager for anxiety at 100mg a day. I feel that pill is the reason I have low T (based on low FSH and LH #'s). I still take it today. I...

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
